Gilles Caulier said I might have visability issue with gcc

visabilty issue with gcc 3.4.6.8 on centos 4.5 trying to
compile
libkipi for a 9.2 version on digikam. What does visability
issue mean? Here is the compile dialog:

I got a gcc4.1 for Centos4.5 after following your
suggestions I get from ./configure
--enable-gcc-hidden-visibility=yes

Your GCC supports symbol visibility, but the patch for Qt
supporting visibility
was not included. Therefore, GCC symbol visibility support
remains disabled.

For better performance, consider including the Qt visibility
supporting patch
located at:

http://bug
s.kde.org/show_bug.cgi?id=109386

and recompile all of Qt and KDE. Note, this is entirely
optional and
everything will continue to work just fine without it.


Good - your configure finished. Start make now

I am not willing to recompile all of qt and KDE to solve
this.
There has to be a better way. Can you suggest a better
solution?

thanks

Would maybe installing CentOS 5.0 help?

Arnd, I had not run make clean before. so I did that.
configured with caulier's option. Ran make. The same result
occured.

About Centos 5.0. I tried to install that version but it
would not recognize my graphics card. I tried everything I
knew about trying to rectify that but it would not run. This
has been a problem with newer redhat releases since fedora
core 5. It does dot even know what monitor I have. All the
previous versions had no problem reconizing my monitor and
graphics card. I am stuck at the current Centos 4.5 level
for now and probably the future.
